[Function study of the peritoneovenous shunt system].

In patients with otherwise therapy-resistant ascites operative methods for reinstillation of ascitic fluid have gained importance in recent years. Most often peritoneovenous shunt systems in the modification "LeVeen" or "Denver" are set in. Clinical evidence for insufficiency of the shunt system can force the radiologist to check the function of the drainage system. The investigation has to be performed under sterile conditions on the fluoroscope table, thus permitting the angiographic assessment of thrombotic complications as well as check of the position and function of the shunt valve and drainage tubes.
